Patented Oct. 3, 1905.

Original application filed September 10, 1896, Serial No. 605,347. Divided and this application filed January 12, 1905. Serial No. 2 LO,74=4.

To all whom it may concern:

Be it known that I, MARK ANTHONY, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Inking-Rollers for Printing-Presses, of which the following is a specification.

This application is a division of an application filed by me September 10, 1896, Serial No. 605,347, for certain improvements in printing-presses more especially designed for printing upon the sides of match-splints or the like. i

The subject of the present application is an inking-roller of simple and eflicient construction, whereby a regular and uniform flow and supply of ink to the type is effected, as will hereinafter appear.

In the drawings, Figure 1 is a plan of the inking-roller and a portion of a type-wheel engaging the same. Fig. 2 is a longitudinal vertical section of the roller. Fig. 3 is a transverse section thereof.

L represents a portion of one of the typewheels of a printing-press, and X the inkingroller with which the wheel engages. This roller comprises a hollow cylinder or shell constituting an ink-reservoir, having at its ends trunnions 0, by which it is rotatably supported in standards N. Surrounding this cylinder or shell is a covering :0 of fibrous or other material having capillary interstices such, for example, as felt. Piercing the wall of the shell at several points, so as to place its interior in communication with the fibrous covering, are opening m :0 which are inclined from radial lines, so as to facilitate the passage therethrough of the fluid ink contained in the reservoir. The inclination of the perforations, as shown in Fig. 3, is outward and rearward with reference to the direction of rotation of the roller, and this arrangement is relied upon I to facilitate the passage of the ink from the reservoir to the exterior absorbing material. It will be understood that if these openings were arranged radially the only force present tending to cause the ink to flow through them would be centrifugal force, owing to the consistency of the ink and the want of sufficient capillary attraction of the openings. WVhen, however, these openings are arranged as described, inertia acts in conjunction with centrifugal force to cause the desired flow of ink, for the reason that as the roller moves more rapidly than the ink within it the openings take up the ink by a scooping action and facilitate its movement outward. Four openings are shown; but this number may be increased or diminished. One end of the roller is in the form of a removable head secured in place by pivot-latches'm 0 I claim- 1. An inking-roller having an internal reservoir from which perforations extend outwardly that incline from lines radial to the center of the roller, substantially as described.

2. In an inking-roller, the combination of an absorbent exterior surface and an interior shell forming an ink-reservoir, the wall of said shell being provided with perforations that incline from lines radial to the center of the roller, substantially as described.

3. In an ink-roller, the combination of an absorbent exterior surface and an interior shell forming an ink-reservoir, the wall of said shell being provided with perforations that are inclined from radial lines and outward and rearward relative to the direction of travel of the roller, substantially as described.
